They all star rookie lawyer Phoenix Wright, who is assigned to a non-stop cavalcade of murder cases.

So, he'll hunt through crime scenes for evidence, then head to court and try and get his client off the hook.

This often involves cross-examining witnesses; finding flaws and contradictions in their stories; and eventually discovering the real killer. It's a bit like Law & Order, only with a wicked sense of humour and an unmistakably Japanese twist.

Take that!

In this iOS HD trilogy - which can be played in either landscape or portrait orientation - Capcom has used high-resolution original artwork.

This new iOS Phoenix Wright collection also sports a bonus feature called "Everyone Object!", where you can share your objections through email and Twitter.

The three-game pack is already out in Japan as a free app. You can buy extra chapters individually, or buy the lot for ¥1500 (about £12).

English-speaking gamers will sadly have to wait until the new year to get their mitts on the trilogy.
